The Armed Conflict Location & Event Data Project (ACLED) is a disaggregated data collection, analysis, and crisis mapping project. ACLED collects information on the dates, actors, locations, fatalities, and types of all reported political violence and protest events around the world. The ACLED team conducts analysis to describe, explore, and test conflict scenarios, and makes both data and analysis open for free use by the public.


ACLED was created by Clionadh Raleigh, a Professor of Political Violence and Geography at the University of Sussex, in 2005 as a component of her PhD work. Since 2014, ACLED has operated as a non-profit, non-governmental organization incorporated in Wisconsin. In 2022, ACLED expanded coverage to the entire world, collecting data in real time and publishing weekly updates. So far, ACLED has recorded a total of more than one million individual events globally.
